Find from amongst the figures, the one which resembles the pattern formed when the transparent sheet is folded along the dotted line.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) →
The answer shows the sheet folded into its top-right quarter, so it is folded along both dotted lines: the left half onto the right, then the bottom half onto the top. Each fold flips the triangle across the fold line, once left to right and once top to bottom; together the two flips turn it upside down with its black and white halves swapped. Being a transparent sheet, the triangle shows through, pointing down with the black half on the left, as in Option (3).
